Southwire Romex SIMpull NM-B 12-Gauge 3-Conductor Cable, 25 ft, Purple

Overview

Southwire Romex SIMpull NM-B cable in a distinctive purple jacket is designed for general residential wiring. This 12‑gauge, 3‑conductor copper cable is commonly used to supply branch circuits for outlets, switches, and other typical loads in homes, stores, and shops. The SIMpull jacket is engineered to ease pulling, stripping, and installation, helping installers save time on dry, above‑ground runs. The cable carries a 600‑volt rating and is intended for normally dry locations, with insulation rated up to 90°C. As specified by the 2011 National Electrical Code, ampacity is limited to the guidance for 60°C conductors. These details can help you plan safe, code‑compliant installations without overextending typical residential use.

Key benefits at a glance

• SIMpull jacket reduces friction during pulling and simplifies stripping and installation.
• Copper NM‑B construction supports common residential branch circuits for outlets and switches.
• Suitable for above‑ground, dry locations with a 600‑volt rating for standard home wiring.
• Can be routed through air voids in masonry blocks or tile walls that are not wet or damp.
• Color may vary slightly across displays; practical color coding can aid project organization.

Practical uses and real‑world scenarios

Use this 25‑foot length to extend power to new outlets during a home remodel, upgrade lighting circuits in an attic space, or wire switches along a hallway. The 12‑gauge copper conductors strike a balance between flexibility and capacity, making it a versatile choice for typical residential circuits. The purple jacket can help with color‑coding in multi‑circuit projects, improving on‑site organization and reducing miswiring risks in busy settings.

Installation considerations and tips

• Plan routes to minimize bends and protect the cable from sharp edges or physical damage.
• Install only in normally dry locations above ground, following local electrical codes.
• Terminations should use compatible connectors and secure protection where required by code.
• Keep the cable away from moisture, wet locations, and potential water exposure to maintain long‑term reliability.

Note: The jacket color is subject to minor variations across displays. This product is intended for dry, above‑ground installations and should be used in accordance with applicable electrical codes and safety practices.
